Product description

Thermal protection device for single- and three-phase standard and explosion-proof (EX) motors equipped with PTC posistor temperature sensors. For motor in EX, the device must be installed outside of the explosion hazard zone.

Technical data

  • thermal protection for motors equipped with winding temperature sensors
  • continuous control of the resistance of the connected sensor in the temperature of the motor windings
  • thermal protection for motors in standard and explosion-proof (EX)
  • trouble indicated by LED indicator
  • signaling of motor overheating on the terminals of the built-in switching contact
  • degree of protection IP20 (DIN rail mounting, 35 mm wide)
  • 1x230V module power supply
  • maximum working temperature 55 C

To protect the motor from overheating, the internal relay (250 VAC / 3 A) switches in the event of a sudden change in resistance. The module sends a signal to switch off the contactor located in the motor power path. After the engine has cooled down and the switch has been reset using the Reset button or by switching off the entire system for 10-15 s, the fan can be restarted.

Note: Contactor, lamp, fuses must be purchased separately.
